A suppressor of axillary meristem maturation promotes longevity in flowering plants
Post-embryonic development and longevity of flowering plants are, for a large part, determined by the activity and maturation state of stem cell niches formed in the axils of leaves, the so-called axillary meristems (AMs) 1 , 2 . The genes that are associated with AM maturation and underlie the diff...

. The genes that are associated with AM maturation and underlie the differences between monocarpic (reproduce once and die) annual and the longer-lived polycarpic (reproduce more than once) perennial plants are still largely unknown. Here we identify a new role for the
Arabidopsis
AT-HOOK MOTIF NUCLEAR LOCALIZED 15
(
AHL15
) gene as a suppressor of AM maturation. Loss of
AHL15
function accelerates AM maturation, whereas ectopic expression of
AHL15
suppresses AM maturation and promotes longevity in monocarpic
Arabidopsis
and tobacco. Accordingly, in
Arabidopsis
grown under longevity-promoting short-day conditions, or in polycarpic
Arabidopsis lyrata
, expression of
AHL15
is upregulated in AMs. Together, our results indicate that
AHL15
and other
AHL
clade-A genes play an important role, directly downstream of flowering genes (
SOC1
,
FUL
) and upstream of the flowering-promoting hormone gibberellic acid, in suppressing AM maturation and extending the plant’s lifespan.
The AHL15 transcription factor is a repressor of axillary meristem maturation.
AHL15
is downstream of flowering genes and prolongs the vegetative growth and longevity of plants, particularly monocarps such as
Arabidopsis thaliana
